Description

  The present invention relates to an opening / closing device and a portable electronic device suitable for a mobile phone, a PDA (Personal Digital Assistant), a portable audio device, and the like.

  Conventionally, various types of portable electronic devices, for example, prevent damage or destruction of the display unit, prevention of damage or destruction of the camera lens, prevention of dust and dust entry, prevention of erroneous key operation, dust on the external connection terminal, etc. , In many cases, a cover mechanism is provided to protect a portion that performs an important function in the device, such as prevention of dust entry. In particular, the cover mechanism is effective in the case of a portable electronic device such as a mobile phone terminal that is always carried by the user and is expected to be used in a hard manner such as when it hits another object in a pocket or bag. It is believed that.

  As a structure of the cover mechanism used in the portable electronic device, there are various structures conventionally. For example, a single cover structure having only one cover member, a plurality of cover members having two or more cover members, and the like. There are cover structures. The operation of the cover mechanism includes a type that opens and closes the cover by rotating the cover member around the rotation fulcrum, and a type that opens and closes the cover by sliding the cover member in the horizontal direction. Furthermore, as a power source for moving these cover members, there are, for example, an electric type using a magnetic force or a motor, and a manual type that the user moves by himself.

  In addition, as a conventional cover mechanism used for a portable electronic device, Japanese Patent Application Laid-Open No. 2003-222930 (Patent Document 1) is provided so as to be rotatable with respect to a housing surface so as to cover an imaging unit. An imaging device is disclosed that includes an imaging cover and a barrier member that can switch an opening of the imaging cover to a closed or open state. That is, according to the imaging device, when the circular imaging cover is manually rotated by a predetermined angle with the center of the circle as the center of rotation, the barrier member is driven by the barrier by receiving the rotational force of the imaging cover. The opening of the imaging cover is opened and closed by rotating about an axis.

JP 2003-222930 A (FIG. 1)

  By the way, the structure for realizing the conventional cover mechanism has many restrictions to be adopted in a device that requires high-density mounting, such as a mobile phone terminal, and is often difficult to mount.

  For example, in the case of a type that opens and closes a cover by rotating a cover member around a rotation fulcrum, there is a restriction that a large amount of space is required on the apparatus housing in order to mount the cover mechanism. One of the causes is the amount of movement of the cover member. That is, for example, if the rotation fulcrum is close to the cover member, the amount of movement of the cover member when the cover is opened increases, and as a result, a space corresponding to the amount of movement is prepared on the device housing. As a result, the structure of the cover mechanism becomes large. Conversely, if the rotation fulcrum is at a position far from the cover member, the amount of movement of the cover member when opening the cover is reduced, but the rotation fulcrum position is far from the cover member, and as a result, the cover mechanism itself The structure itself becomes larger.

  For example, in the case of a type that opens and closes a cover by sliding one cover member in the horizontal direction, it is common that the sliding direction of the cover member coincides with the cover opening and closing operation direction. There is a problem that the degree of freedom in deciding the design of the device casing is reduced.

  The present invention has been proposed in view of such circumstances, and by reducing the size of the cover mechanism, for example, it can be adopted in a portable electronic device that requires high-density mounting, and the device housing. It is an object of the present invention to provide an opening / closing device that can increase the degree of freedom of body design and a portable electronic device including the opening / closing device.

The portable electronic device according to the present invention includes a housing in which a camera lens is installed, and a boss portion that is disposed outside the housing portion in which the camera lens is installed, and protrudes from the surface. Provided, the opposite end of each of the two or more cover members abuts or partially overlaps the closed state in which the camera lens is covered, and the opening that exposes the camera lens by separating each opposite end. Cover means capable of taking a state and a boss portion of each cover member are fitted through a first through groove portion provided in the apparatus housing, which is arranged inside the housing portion where the camera lens is installed. It has been made so as to move the ring members each cover member in the second direction to the closed state in conjunction with the rotation of the first direction parallel to the circumferential direction of the predetermined ring member, the first direction In the third direction, opposite to The cover member driving means for moving each cover member in the fourth direction which is opened in conjunction with the rotation of the ring member and the camera lens are disposed outside the casing portion where the camera lens is installed.

That is, according to the present invention, the first and third directions for rotating the ring member are different from the second and fourth directions for opening and closing each cover member of the cover means. The first and third directions, which are the operating directions of the operating force when rotating the ring member, are converted into the second and fourth directions, which are the operating directions of the operating force when opening and closing the cover means.

  In the present invention, since the cover member can be opened and closed by moving the cover member in a direction different from the rotation direction of the ring member in conjunction with the rotation of the ring member, the cover mechanism can be downsized. Therefore, it can be applied to a portable electronic device that requires high-density mounting. Further, in the present invention, it is not necessary to match the direction of operation force for opening and closing the cover mechanism and the opening and closing direction when the cover mechanism actually opens and closes, so that the degree of freedom in designing the device housing is reduced. It becomes possible to raise.

  Hereinafter, with the state where the cover mechanism of the present embodiment is incorporated in the terminal housing 1 and the vicinity of the boss slide groove portion 41a of the lever ring 40 being seen from the back side, FIGS. A state of movement of the first cover member 3a due to the boss portion 21a sliding according to the rotation of the lever ring 40 will be described.

  First, FIG. 12 shows a state in which the boss portion 21a of the first cover member 3a is located on the inner peripheral side of the boss slide groove portion 41a of the lever ring 40. In this state, when the user slides the slide knob 2 and, for example, the lever ring 40 is rotated in the direction indicated by the solid line arrow 70 in FIG. 13, the boss portion 21a of the first cover member 3a is It moves along the boss slide groove 41a as indicated by a solid arrow 71 in FIG. That is, the first cover member 3a at this time moves in the direction indicated by the solid line arrow 71 in FIG. Further, when the user slides the slide knob 2 from the state shown in FIG. 13 and the lever ring 40 is rotated in the direction indicated by the solid line arrow 73 in FIG. 14, for example, the boss portion of the first cover member 3a. 21a further moves along the boss slide groove 41a as indicated by a solid arrow 72 in FIG. That is, the first cover member 3a at this time moves in the direction indicated by the solid line arrow 72 in FIG.

  On the other hand, when the user slides the slide knob 2 in the state shown in FIG. 14 and the lever ring 40 rotates, for example, in the direction shown by the one-dot chain line arrow 74 in FIG. 14, the first cover member 3a. The boss portion 21a moves along the boss slide groove portion 41a as indicated by a one-dot chain line arrow 75 in FIG. That is, the first cover member 3a at this time returns to the position shown in FIG. Further, when the user slides the slide knob 2 from the state shown in FIG. 13 and the lever ring 40 is rotated in the direction indicated by the one-dot chain line arrow 76 in FIG. 13, for example, the boss of the first cover member 3a. The part 21a further moves along the boss slide groove part 41a as indicated by a one-dot chain line arrow 77 in FIG. That is, the first cover member 3a at this time returns to the position shown in FIG.

  As described above, according to the cover mechanism of the present embodiment, the first cover is converted by converting the slide operation in the arc direction by the slide knob 2 into the linear motion of the first cover member 3a and the second cover member 3b. The opening / closing operation | movement of the member 3a and the 2nd cover member 3b is implement | achieved.

  In the cover mechanism of the present embodiment, the angle A between the center line L2 of the boss slide groove portions 41a and 41b of the lever ring 40 and the circumferential tangent L1 of the lever ring 40 is limited to the angle shown in FIG. For example, it may be a steeper angle or a gentler angle. If the angle between the center line of the boss slide groove portions 41a and 41b of the lever ring 40 and the circumferential tangent of the lever ring 40 is steep (approaching 90 degrees), the slide operation speed of the slide knob 2 (lever ring 40). The opening / closing relative speed of the first and second cover members 3a, 3b with respect to the rotation speed of the slide knob 2 can be increased. Conversely, if the angle is made gentle, the slide operation speed of the slide knob 2 (the rotation of the lever ring 40) can be increased. The opening / closing relative speed of the first and second cover members 3a, 3b with respect to the (moving speed) can be reduced.

  Further, in the cover mechanism of the present embodiment, the shape of the boss slide groove portions 41a and 41b of the lever ring 40 is not limited to the substantially linear shape as shown in FIG. 9, but is, for example, like the boss slide groove portion 41c shown in FIG. It may be a simple curve. FIG. 15 shows only the vicinity of one boss slide groove 41c of the lever ring 40. When the boss slide groove portions 41a and 41b are curved, even if the slide operation speed of the slide knob 2 is, for example, constant (the rotation speed of the lever ring 40 is constant), the first and second cover members 3a, 3b can change the speed from the closed state to the end of opening and the speed from the open state to the end of closing. When the boss slide groove 41c in the example of FIG. 15 is adopted, the moving speed of the cover member when shifting from the open state to the closed state is initially fast and then slow, while when moving from the closed state to the open state. The moving speed of the cover member is initially slow and then fast.

  Furthermore, in the cover mechanism of the present embodiment, the boss slide groove portions 41a and 41b of the lever ring 40 can have different shapes and angles between the boss slide groove portions 41a and 41b. In this case, the speeds when opening and closing the first and second cover members 3a and 3b are different.

[Comparison of the cover mechanism of this embodiment and other cover mechanisms]
Hereinafter, with respect to the cover mechanism of the present embodiment and other cover mechanisms, changes in the external size when the cover is opened and closed will be compared and examined using FIGS.

  FIG. 16 shows a state when the cover mechanism of this embodiment is opened and closed. On the other hand, FIG. 17 and FIG. 18 show a conventional type cover mechanism that opens and closes the cover by rotating the cover member around the rotation fulcrum. In the example of FIG. 17, the rotation fulcrum is the cover member. When it exists in one edge part position (distance 0mm), the example of FIG. 18 has shown the case where a rotation fulcrum exists in the position (distance Pmm) far from a cover member.

  Here, when the first and second cover members 3a and 3b of the cover mechanism of the present embodiment are opened and closed, and the amount by which the outer size of the cover mechanism changes is, for example, Lmm, the example of FIG. In the cover mechanism, the change amount of the outer size due to opening / closing of the cover is Nmm (N> L), and in the cover mechanism of the example of FIG. 18, the change amount of the outer shape size due to opening / closing of the cover is Mmm (M> L). In the case of the example in FIG. 18, the amount of change in the external size due to opening and closing of the cover is Mmm (M <N), and the angle at which the cover member rotates about the rotation fulcrum is E degrees (D> E). The amount of change in the outer size (Nmm) and the rotation angle (D degrees) are both smaller than in the example of FIG. 17, but in the example of FIG. 18, the position (distance Pmm) from the rotation fulcrum to the end of the cover member is included. The cover mechanism itself is larger. On the other hand, in the case of the cover mechanism of this embodiment, the outer size of the cover mechanism due to opening and closing of the cover has the smallest amount of change, and the size of the cover mechanism itself is also the smallest.

[Summary]
As described above, the cover mechanism of the present embodiment is small and can effectively cover the member to be covered, and thus can be employed in a portable electronic device that requires high-density mounting. . Further, the cover mechanism of the present embodiment does not require the operation direction (that is, the sliding direction of the slide knob 2) when opening / closing the cover to depend on the opening / closing direction of the cover member. According to this, while the opening / closing operation direction of the cover is a linear motion, the sliding direction of the slide knob 2 can be an arc direction, so that there are few restrictions when deciding the design of the terminal housing, and it is free It is possible to adopt a simple design.

  Furthermore, the cover mechanism of the present embodiment can be composed of at least two of the first and second cover members 3a and 3b, the slide knob 2, the lever ring 40, and the housing 1 in total, saving space and cost. And stable quality with a small number of parts can be realized. In other words, the cover mechanism of the present embodiment is optimal for portable electronic devices in which the structure is small, functions are incorporated in a small space, and the overall size is to be minimized.

  The above description of the embodiment is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made according to the design or the like as long as the technical idea according to the present invention is not deviated.

  For example, the cover mechanism of the present invention is not limited to a mobile phone terminal, and can be applied to various portable electronic devices such as PDAs, portable audio devices, digital cameras, and the cover mechanism of the present invention is the lens described above. In addition to the mirror and the mirror, various covered members such as a key, a display unit, and an external connection terminal can be protected. Of course, the cover mechanism according to the present invention can be applied not only to the purpose of protecting the covered member but also to an opening / closing mechanism of an insertion port of an external memory or a disk medium.

  Moreover, although the cover mechanism of this embodiment gave the example which converts the slide operation to the circular arc direction in the slide knob 2 into the linear motion of the 1st, 2nd cover members 3a and 3b, the slide operation direction of the slide knob 2 was given. Is not limited to a circular arc, and may be a linear direction. Further, the linear operation direction of the slide knob 2 is a predetermined angle such as 90 degrees with respect to the linear movement direction of the first and second cover members 3a and 3b (that is, the first 1 and a direction different from the linear motion direction of the second cover members 3a and 3b). In this case, for example, a method of providing a gear on the outer peripheral side of the lever ring 40 and converting the linear motion of the slide knob 2 into the rotational motion of the lever ring 40 via the gear is applicable.

  Furthermore, although the cover mechanism of the present embodiment gives an example in which the user slides the slide knob 2, the slide knob 2 for user operation is not provided, and for example, a ring-shaped ultrasonic motor or the like is attached to the lever ring 40. It is also possible to rotate the lever ring 40 by driving the ring-shaped ultrasonic motor by attachment, switch operation or the like. Alternatively, the lever ring 40 can be rotated by a normal motor, a gear mechanism, a spring member, etc., and the lever ring 40 can be rotated by driving the motor by a switch operation or the like, or by the force of the spring member. It is.

  Further, the cover mechanism according to the present invention is not limited to the one provided with two cover members as in the above-described embodiment, and for example, three or more cover members may be opened and closed in conjunction with the slide operation of the slide knob. Is possible. That is, in this case, the lever ring has boss slide groove portions corresponding to the boss portions of the three or more cover members, and the boss portions of the cover members are slidably fitted into the boss slide groove portions. .
